Cholesterol Blood Test
Cholesterol blood test in Plymouth
A cholesterol blood test in Plymouth measures your total cholesterol, LDL (“bad” cholesterol), HDL (“good” cholesterol), triglycerides, and cholesterol ratio to assess your cardiovascular risk. This is one of the most important preventative health checks available — high cholesterol often causes no symptoms but significantly increases your risk of heart disease and stroke. Our private cholesterol blood test requires no referral and gives you a complete picture of your heart health risk in just one appointment.
Why this test matters
Cholesterol is often called “silent” because you can have dangerously high levels without feeling anything. By the time you have symptoms of heart disease, the damage may already be done. This test catches the problem early so you can make lifestyle changes or start treatment before problems develop. Knowing your LDL, HDL, and triglyceride levels helps your clinician calculate your real cardiovascular risk — not just your cholesterol number, but the balance between protective and harmful cholesterol types.
What this test measures
This comprehensive lipid panel measures five key markers that together reveal your cardiovascular risk. Each marker tells a different part of the cholesterol story.
| Marker | What it measures | Why it matters |
|---|---|---|
| Total cholesterol | The sum of all cholesterol in your blood (LDL + HDL + triglycerides) | A screening marker, but not as important as LDL and HDL separately. Some people with high total cholesterol have protective high HDL and low LDL. |
| LDL cholesterol (“bad”) | Low-density lipoprotein, the main form of cholesterol that builds up in arteries | The most harmful cholesterol type. High LDL increases risk of heart attacks and strokes. Lower is generally better — ideally below 3.0 mmol/L for most people. |
| HDL cholesterol (“good”) | High-density lipoprotein, which removes cholesterol from arteries | Protective against heart disease. Higher HDL is better — ideally above 1.2 mmol/L. People with high HDL have lower cardiovascular risk even if total cholesterol is higher. |
| Triglycerides | A type of fat in the blood that rises after eating fatty food | High triglycerides increase cardiovascular risk and are often linked to insulin resistance and type 2 diabetes. This is why fasting is required — triglycerides spike with food. |
| Total cholesterol to HDL ratio | Your total cholesterol divided by your HDL cholesterol | Shows the proportion of “bad” cholesterol to “good.” A lower ratio indicates better cardiovascular health. Below 5 is ideal; below 3 is excellent. |
Who should get this test?
The NHS recommends cholesterol screening for all adults aged 40 and over, and for younger people with risk factors. However, many people benefit from knowing their levels earlier, especially if they have family history or lifestyle factors that increase cardiovascular risk.
- Over 40 years old
- Family history of heart disease
- Family history of high cholesterol
- High blood pressure
- Overweight or obese
- Type 2 diabetes or pre-diabetes
- Current smoker
- Sedentary lifestyle
- Previous cardiovascular event
- Stress or mental health concerns
What your results mean
Understanding your results
Your results will show numbers alongside interpretation — typically “desirable,” “borderline,” or “high” for each marker. However, the interpretation depends on your individual risk factors. Someone with LDL of 3.5 mmol/L might need treatment if they have diabetes or a family history of heart disease, but might be fine if they’re young and have no other risk factors. Our clinician reviews all your results in context and explains what your numbers mean for your personal cardiovascular risk.
If your cholesterol is high, the first step is usually lifestyle modification — diet changes (especially reducing saturated fat and increasing fibre), regular exercise, and weight loss if needed. If lifestyle changes aren’t enough, or if your LDL is very high or you have multiple risk factors, statin medication may be recommended. If triglycerides are very high, there may be metabolic issues to explore. Your clinician will discuss all options with you.
What happens at your appointment
Arrive at our Estover clinic in Plymouth having fasted overnight (just water is fine). Our clinician will discuss your cardiovascular risk factors, family history, lifestyle, and any symptoms. The blood draw is quick and straightforward — usually less than five minutes. We take the sample from a vein in your arm and send it to our laboratory for analysis.
Your results are typically ready within 24–72 hours. You’ll receive them either at a follow-up appointment where we discuss the numbers in detail and create a plan to reduce your cardiovascular risk, or online if you prefer. Whether your results are reassuring or require action, we explain everything in plain English. If lifestyle changes or medication are needed, we’ll discuss options, potential side effects, and how often you should have repeat testing.
Frequently asked questions
Why do I need to fast before a cholesterol test?
Fasting is essential for accurate triglyceride measurement. Triglycerides rise dramatically after eating, especially fatty food, and can give a falsely high reading if you’ve eaten recently. By fasting 9–12 hours, we measure your baseline triglyceride level. Cholesterol and HDL are less affected by fasting, but most labs ask you to fast for all lipid panels to give the most reliable results.
Can I drink coffee or water while fasting?
Water is fine — drink as much as you like. Black coffee (without milk or sugar) is usually acceptable. However, coffee with milk, sugar, juice, or any other beverages should be avoided as they can affect results. To be safe, ask when you book — different labs have slightly different rules.
What cholesterol level is normal?
Total cholesterol below 5.2 mmol/L is considered desirable, though this is just one marker. More important is LDL below 3.0 mmol/L and HDL above 1.2 mmol/L. If you have heart disease or diabetes, your targets may be even stricter. Your clinician will explain your personal targets based on your risk factors.
If I have high cholesterol, will I definitely need statins?
Not necessarily. If you’re younger, have no other risk factors, and are willing to make serious lifestyle changes, it’s reasonable to try diet and exercise first. However, if you have diabetes, existing heart disease, very high LDL, or multiple risk factors, medication is often recommended. Your clinician will discuss your options based on your individual situation.
How often should I have my cholesterol checked?
If you’ve never been screened, once is a baseline. If your results are normal and you have no risk factors, checking every 5 years is reasonable. If results are borderline or high, annual testing helps monitor your progress with lifestyle changes or medication. If you’re on statins, annual or 6-monthly checks monitor effectiveness and side effects.
